Texture corruption issue: add tests for a few rendering types

The original tests for texture corruption only contain WriteTexture
and B2TCopy, this change adds more write types like rendering a
constant color, rendering from texture sampling, and rendering
from textureLoad, all of which need a render pipeline and shaders.

The new tests manifest that:
For a given 2d-array texture dimension, if WriteTexture and B2TCopy
fail, rendering, sampling and textureLoad also fail, and vice versa.
